Abstract
HgS and HgS: Co crystals and films grown by the slow cooling and the chemical bath deposition method were used to measure their crystal structure and their optical absorption spectra. HgS and HgS: Co crystals are hexagonal structure with the lattice constant $a_0=4.155{\AA}$, $c_0=9.505{\AA}$ for HgS and $a_0=4.148{\AA}$, $c_0=9.462{\AA}$ for HgS and $a_0=4.135{\AA}$, $c_0=9.442{\AA}$ for HgS: Co, respectively. The optical energy gap of these crystals are given as 2.040 eV for HgS and 1.900 eV for HgS: Co, and the optical energy gap of these films were 2.440 eV for HgS and 1.940 eV for HgS: Co at room temperature, respectively.
서냉법과 용액성장법으로 HgS 및 HgS : Co 결정과 박막을 성장시켜서 결정구조를 조사하고 , 광흡수를 측정했다. 이들 결정 및 박막은 육방정계 구조로써 HgS 및 HgS : Co 결정의 격자상수는 각각 $aa_0=4.155\AA$, $c_0=9.505{\AA}$과 ao=4.148$\AA$, co=9.487$\AA$ 이었다. 또한 HgS 및 HgS박막에 대한 격자상수는 각각 $a_0=4.148{\AA}$, $c_0=9.462{\AA}$와 $a_0=4.135{\AA}$, $c_0=9.442{\AA}$으로 주어졌다. 293K에서 측정된 광학적 에너지 간격은 HgS 및 HgS : Co 결정이 2.040eV, 1.900eV 이고, HgS 및 Hgs : Co 박막은 2.440, 1.940eV 로 각각 주어졌다.
